VALVE.

SPECIFICATION forming part of Letters latent No. 604,592, dated May 24, 1898. Application filed December 27, 1897. Serial No. 663,607. (No model.)

To aZZ whom it may concern.-

Be it known thatwe, HENRY J. SOHMITT, residing at Hoboken, in the county of Hudson, and RUssELL BoNNELL, residing at Elizabeth, in the county of Union, State of New Jersey, citizens of the United States, have invented certain new and useful Improvements in Valves; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to valves; and it consists in the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure 1 is a longitudinal section through the valve. Fig. 2 is a sectional plan view taken on line 5c 00 in Fig. 1.

A is the valve-casing, provided with converging valve-seats a.

B are two disks having lugs 19 on their backs.

0 is a hollow wedge-shaped carrier which is arranged loosely between the two disks B. The lugs 17 have shoulders I), which engage pivotally with the carrier, so that the disks are free to rock to a limited extent, and the lugs have rounded ends 0, which bear against the backs of the opposite disks, to which the lugs are not attached.

D are projections on the carrier, and d are guides on the casing. The projections slide in the guides, so that the carrier is only free to move vertically.

E are pins which pass through holes in the carrier and in the lugs I). These pins are not pivots, and they merely couple the disks to the carrier when removed from the casing, so

0 that the disks may not fall apart from the carrier and become lost.

Any approved means can be used for raising and lowering the valve, and when a valvestem is used it is immaterial whether the stem 5 moves vertically or not.

The valve-stem F does not move vertically, and it is provided with a screw-threaded portion f, which engages with the carrier 0.

G is the handle or wheel for revolving the valve-stem.

When the valve-stem is turned so as to press the carrier downward, the disks are pressed firmly against the valve-seats and bear with equal pressure all around the seats.

When the carrier and disks are raised in the casing, an unobstructed passage through the seats is provided. The lugs on the disks are spaced so as to clear the valve-stem when the carrier and disks are raised.

What We claim is- 1. The combination, with a valve-casing provided with seats, of a hollow carrier, and disks provided with lugs which have shoulders arranged near the peripheries of the disks and engaging pivotally with the carrier, the lugs on each disk being arranged to overlap the lugs on the other disk and to bear against its central portion, whereby both disks are pressed uniformly upon the said seats, substantially as set forth. 7o

2. The combination, with a valve-casing provided with seats, of a hollow carrier, disks provided with lugs which have shoulders arranged near the peripheries of the disks and engaging pivotally with the carrier, the lugs on each disk being arranged to overlap the lugs on the other disk and to bear against its central portion, and a pin passing loosely through holes in two of the said lugs and the side of the carrier and preventing the disks from falling apart from the carrier when the carrier is removed from the valve-casing, substantially as set forth.

In testimony whereof we affix our signatures in presence of two witnesses.
